摘要
应用典型的辐射资料质量检验方法、辐射数据变化特征分析、人工与器测日照对比分析及太阳总辐射与相关辐射要素间的统计分析对天津市宝坻国家级基本气象站站内的太阳辐射观测系统试运行期间的辐射观测数据进行了质量分析,结果表明,试运行期间数据到报情况理想,总、散射辐射观测数据的BSRN的质量检验合格率为100%,直接辐射合格率为85%,净辐射通过了仪器阀值质量检验;太阳辐射值及变化特征符合理论实际;人工与器测日照时数具有很好的线性相关性(R2=0.96),总辐射与日照时数及散射辐射之间的线性变化与历史经验结论吻合。总体来看,宝坻太阳辐射系统观测数据可用性较高,能够满足日常业务需求。
Several methods such as the typical radiation data quality method, radiation data variation analysis, comparison of Sunshine duration between the manual and instrument measurements, and statistical analysis of solar global radiation and the other radiation are used to analyze the quality of the solar radiation data in the Baodi Meteorological Station （54525）. The results show that during the test run, there was few missing data; 100 % of global radiation and diffuse radiation and 85 % of direct radiation passed the BSRN recommended QC tests and 100% net radiation passed the equipment observation threshold test; the solar radiation variation corresponds to reality; the manual and instrument sunshine duration measurements have good consistency; the linear changes among the global radiation, diffuse radiation, and the sunshine duration are the same with the classic study results. Overall, the data of this radiation observing system has high availability and can fulfill the daily business needs.
